I have a Polar s720i HRM with the speed sensor and cadence sensor
mounted on my road bike. For the past week I notice that I seem to be
getting faster than normal speed readings. Although I wish this was a
sign of improved performance on my part, I seriously doubt I could be
riding that fast, (for example, it says I'm doing 50km/h when I
know there is no way I could be going that fast, especially on a
climb).
I haven't altered my wheel circumference settings, and I know the
wrist unit is working fine because I also use it with my mountain
bike, which has its own speed sensor, and I get normal readings from
that. I realise that with wireless devices such as this you get the
occasional fast reading, especially when riding under power lines; but
these fast readings seem to be happening during my entire bike ride.
Is this a sign that the speed sensor's battery is dying? Or some
other bigger problem?
